Abstract Pancreatic beta cell loss of life is certainly a hallmark of type 1 and 2 diabetes (T1D/T2D), however the underlying molecular mechanisms are understood incompletely. Key proteins from the DNA harm response (DDR), including tumor protein P53 (P53, also called TP53 or TRP53 in rodents) and Ataxia Telangiectasia Mutated (ATM), a kinase recognized to action of P53 upstream, have been linked.
